AU received a complaint that a public-school district’s computer system blocked student access to Scientology websites because it classified Scientology as a “cult,” while allowing free access to the websites of other religions. We wrote to the district to explain that government classification of a particular religion as a cult raises serious constitutional questions, and that application of the district’s website filtering policy in a discriminatory manner violates the Free Exercise Clause. In response, the district assured us that the filters no longer block Scientology websites.
